    Does any one know what these 3 circuit symbols mean?

    Could you post some context please? A circuit they're shown in, for example? It'll help a lot I think.

    I think somebody has made them up! They certainly aren't symbols to any standard I've come across.

    I was thinking the same thing, which is why I asked for context. They certainly aren't standard schematic symbols.

    Think laterally

    Killroy?

    Banksie?

    Actually number 1 looks familiar...

    I'll have a think in the morning.

    Hmmm...

    Given that this is posted in the Math forum, hmmm.....

    Nope, nothing comin' to mind.

    I think they are laser optic component symbols.
    #1 might be a side-by-side variable combiner.
    #2&3 boxes with hashes might be beam splitters.

    That makes reasonable sense. Maybe that will be enough to tickle someone the right way and come up with something more concrete. I will probably try to follow that line of reasoning a bit, too, and see if I come up with anything.

    Number (1) looks a bit like a crossbar switch--phone people use funny symbols from time to time.

    Or it could be a guy who tried peeing on an electric fence!:D

    Obviously one half of both (2) & (3) looks like a LED,but the "#s" don't mean anything to me!

    The suggestion of something to do with laser optics sounds good.

    I think the "#s" indicate polarization or beam rotation. I've got a fuzzy memory of this from when I worked on some laser reflectometry gear years ago.

    The schematics show where the symbols come from. Its part of traction converter/inverter system.

    Completely wrong..again... wow! :confused:

    Maybe a magnetic device like a ferrite and opto isolator, at least I was close with an optical symbol.

    #1 is probably juts a test point or something. I don't think it's an actual component. The second and the third might be optocouplers, but it's very difficult to tell. Those schematics are a mess, I can't read half of it. And they certainly don't use standard symbols.

    I see that the top symbol in the original diagram is used on its side in the second full drawing.

    I would suggest that it refers to a bus cable, perhaps for a wiring loom.
